As an additional point—“bear fat”, specifically, is impractical for reasons I think even an alien with a modest understanding of Earth’s biosphere could guess (I mean, have you seen a bear, Mr. Alien?). But “pork fat” is an exceedingly common ingredient, and not too far off. So “lard with honey and salt” or “tallow with honey and salt” would be very much possible to mass produce, and yet it’s the ice cream that prevails. There may be something there, I’m sure lard with honey and salt is perfectly viable and possibly even made in some circumstances? But ice cream feels more “casual”, I think milk-based fats are more digestible than the ones straight from the meat. Lard just doesn’t scream “refreshing thing you eat while on a walk”.
